If I'm not mistaken this was introduced with this commit: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/if_em.c.diff?r1=1.269&r2=1.270 Without trying to sound like the chicken [1], if you're adventurous enough, you can always enable it for I350 and 1) recompile 2) try 3) report back / send in diff :) Daniel [1] https://en.wikipedia.org/wiki/The_Chicken_and_the_Pig -- LÉVAI Dániel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F
